I wanted to automatically generate certain timing values used by LaunchPad-targeted code. The purpose is to operate a software FLL on the MSP430G22x1 cpu, which requires one integer multiplier, and to properly operate the asynchronous serial port communications (to the virtual COM port on a PC) with another integer divisor. The way I chose to run the serial communications was to divide SMC...

Hello, I recently bought digital caliper and decided to try to read it's data port readings from my Launchpad. It had Clock and Data pin. Had to setup pin that connects to Clock to trigger interrup on every pulse and then in interrupt function do bit shifting to assemble 16 bit signed integer representing caliper reading. Then sent it out to PC via soft UART serial port. You can find full sourc...

I am interested in building a small application (basically a simple USB PC peripheral) directly with the MSP430 series launchpad module MSP-EXP430G2. Is there anywhere I can find information that would help me use the USB interface in an application (that is, what it "looks like" from the PC end of things, and what it "looks like" from the MSP430 end of things? Linux (for the PC) would be ideal...

What am I doing wrong or not doing at all? I want to use GCC free compiler for the MSP-430 family and especially for the TI Launchpad MSP430F5529. I have never used GCC before. Also, where is a list of c commands for this processor? Thanks for any and all help. Joe

Hey everybody, About two weeks ago I started making a serious effort to learn to use the MSP430 Launchpad (with MSP430F2012). I have no prior experience coding in C or C++, so I wanted to describe what I've learned, and get some feedback, just to make sure I understand everything correctly. In the "blink your first LED" tutorial there is the following piece of code: P1DIR |= 0x01; It explai...

Hello, I did a search but I couldn't seem to find it or I didn't search correctly. Anyways, I am currently going over some sample for the launchpad and looking over the .h file for the msp430g2231. I am doing the conversion from hex to binary to get a better visualization of what it is setting what bit in the registers. The question I am facing right now is that under the ADC10 section of t...

Hi, all! I am a hobbyist and I picked up two Launchpads to start learning uPs in my retirement. If I were to program the chip that came with the launchpad to just loop a program that toggled the state of a pin (i.e. pin = !pin), what is the minimum reasonable, ball park, SWAG, frequency should I expect to see on the pin? Can I get at least 1 MHz? Thanks, in advance, Mike -------------...

Hi, I'm looking for a 4bit LCD "c" code to drive a hd47780 LCD with Launchpad. Is there any "C" library available? I check the files section but only found assembly code. Any pointers would be appreciated. Thanks. Chetan ------------------------------------

I have just recently picked up a TI MSP430 Launchpad. I am new to programming microprocessors. I was wondering if someone can give me a few hints on PWM. I understand some of the basic principles of PWM in general, but I am having a hard time putting them to practice using TI's MSP430 family user's guide. I am trying to control a continuous rotation servo from parallax. The servo requires ...

I gather that the Microcrystal MS3V-T1R was used here: PDF datasheet at: http://www.microcrystal.com/CMSPages/GetFile.aspx?nodeguid=21218980-0886-41a2-87fc-6b04e14f0226 Anyway, these appear to come in 7pF, 9pF, and 12.5pF varieties. My natural assumption, given that the MSP430's used in the MSP-EXP430G2 kit come out of reset configured to use 6pF on LFXT1, that TI would have selected th...

Has anyone got this working reasonably on any Linux? I'm using CentOS. I got it to create a project, build, load and run the OutofBox demo for the F5529 LaunchPad, but that is all. I'm not even sure I could reproduce that :-( I had loaded a blinky demo using Energia, so it really did load and build the OutofBox demo. The first time I pressed button 2 to get the rocket, it kernel panicked my...

Hello, I just received my LaunchPad board and of course I joined this group. I'm a veteran software engineer with some hardware experience (physical circuit building, not just embedded or firmware coding) but I'm new to MSP430 development. What's the best development environment? Code Composer, IAR, MSPGCC, or Energia? Here are my initial thoughts, 1. Code Composer has the needed device driv...

Well... I finally finished my first MSP430 project, a VLF (Very Low Frequency) transmitter with built-in morse code identifier. This allows anyone to generate a signal in the U. S. "license-free" radio spectrum between 160 and 190 KHz using only the Launchpad. It allows you to configure settings using a (I think) clever menu system with the S2 pushbutton as the only input device to select b...

So I have some code running well when in debug mode connected to my computer. I then unplug the usb cable from the computer and plug it into a wall usb charger and the code behaves differently. Still using the launchpad, checked the voltage and its correct. Several if statements as well as the watchdog timer setup as an interval timer are not working. Where should I start with trying to work t...

What sort of jitter should I see using ACLK on timer A w/ the 32 KHz xtal in place? I'm seeing ~1.5 us on the falling edge of a nominally 30.5 us pulse. I'm generating a pulse train using timer A in up mode driving LED2. I expect to see jitter in the pulse length using SMCLK derived from the DCO at the 8 MHz calibrated frequency, but I also see it if I change to ACLK for timer A (still DCO fo...
